Endoparásitos de una población de cerdos silvestres (Sus scrofa) en Bahía Samborombón, Buenos Aires, Argentina

Abstract

In Argentina little is known about the parasitofauna in wild pigs. This work discloses parasitic species in a wild population of Sus scrofa in the Bahía Samborombón protected area. Fecal samples were taken from 30 individuals and their viscera were prospected. The total prevalence (P) was 90%, with a specific richness of 11. In the coprological analysis were detected: Eimeria sp. (P = 18.5%), Isospora sp. (P = 22%) (Coccidia), Iodamoeba sp. (P = 52%) (Amoebidae), Macracanthorhynchus hirudinaceus (P = 33%) (Acanthocephala), Ascaris suum (P = 22%), Oesophagostomum dentatum (P = 4%), Globocephalus sp. (P = 7.5%), Metastrongylus sp. (P = 7.5%), Hyostrongylus sp. (P = 18.5%), and Trichuris sp. (P = 4%) (Nematoda). In the helminthological prospections were observed juveniles and adults of M. hirudinaceus (P = 33%) and A. suum (P = 23%); O. dentatum (P = 3%) and hydatid cysts of Echinococcus sp. (P = 20%) (Cestoda, Taeniidae). The association values of the Fager index were not significant except for the pair Isospora sp.-Eimeria sp. The present study shows that the population of wild pigs of Samborombón Bay presents a high richness of parasitic species, many of which have zoonotic importance such as Eimeria sp., Isospora sp., Macracanthorhynchus sp., Ascaris sp., and Echinococcus sp.

“…(2%), and Macracanthorhynchus hirudinaceus (21%). In Samborombón Bay (Argentina), during the autopsy and stool examination ( n = 30), the following helminths were reported [ 28 ]: Macracanthorhynchus hirudinaceus (33%), Ascaris suum (22%), Oesophagostomum dentatum (4%), Globocephalus sp. (7.5%), Metastrongylus sp.…”

New morphological and molecular perspectives aboutMacracanthorhynchus hirudinaceus(Acanthocephala: Oligacanthorhynchidae) from wild boar,Sus scrofaLinn., in Ukraine

“…Males were 50-90 mm long by 6-8 mm wide and females reached 650 mm long by 7-8 mm wide and the proboscis was slightly longer than wide measuring 600-1000 long by 50-92 wide and with six spiral rows of six hooks each and with the largest hook reaching 320 and the smallest basal hook reaching 260; the eggs were 92-110 long by 50 wide (Naidu, 2012). The eggs from specimens from Buenos Aires, Argentina averaged 108 long (erroneously listed as 10.8) by 51.6 wide (Ciocco et al, 2019). In southwestern Iran, Sarkari et al (2016) reported 52-89 (68) long by 2-3 (2.8) wide males and 56-351 (205) long by 3-6 (4.6) wide females, and proboscis length of 580-830 (730) in males and 660-950 (820) in females; width measurements were not given.…”

“…Los grandes mamíferos que comparten territorio en áreas rurales, autóctonos o introducidos, pueden portar parásitos, en especial el cerdo (Ciocco et al, 2019) y transmitirse enfermedades como brucelosis, sarna y otras. De las especies presentes (ovinos, vacunos, cánidos, felinos, ciervo axis, Figura 6.…”
